AAT4282A  
Dual Slew Rate Controlled Load Switch  
SmartSwitch  
General Description  
Features  
The AAT4282A SmartSwitch™ is a member of  
AnalogicTech's Application Specific Power MOS-  
FET™ (ASPM™) product family. The AAT4282A is  
a dual P-channel MOSFET power switch designed  
for high-side load-switching applications. Each  
MOSFET has a typical RDS(ON) of 60mΩ, allowing  
increased load switch current handling capacity with  
a low forward voltage drop. The device is available  
in three different versions with flexible turn-on and  
turn-off characteristics – from very fast to slew-rate  
limited. The standard 4282A (-1) version has a slew-  
rate limited turn-on load switch. The AAT4282A (-2)  
version features fast turn-on capability, typically less  
than 500ns turn-on and 3µs turn-off times. The  
AAT4282A (-3) variation offers a shutdown load dis-  
charge circuit to rapidly turn off a load circuit when  
the switch is disabled. An additional feature is a  
slew-rate selector pin which can switch between fast  
and slow slew rate.

Smartphones  
All the AAT4282A load switch versions are  
designed to operate from 1.5V up to 6.5V, making  
them ideal for both 3V and 5V systems. Input logic  
levels are TTL and 2.5V to 5V CMOS compatible.  
The quiescent supply current is a very low 1µA.  
The AAT4282A is available in the Pb-free, low pro-  
file 2.0x2.0mm FTDFN22-8 package and is speci-  
fied over the -40 to 85°C temperature range.
